Mitigating Controls (NIST 800-53 r5) AI

prevent

Enforces memory protections that directly block invalid kernel address dereferences in device drivers such as issimian.

prevent

Requires validation of all input to kernel interfaces, preventing malformed addresses from reaching the vulnerable driver path.

prevent

Restricts the privileges under which processes can invoke the Exynos issimian driver, limiting the scope of a successful dereference to DoS.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent introduction of untrusted pointer handling during development.

DE.CM-09 partial match
prevents

Runtime monitoring of software and data can detect adverse events resulting from exploitation of the weakness.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover instances of this weakness via code review or scanning.

detects

Security testing can detect pointer-dereference flaws before release.

prevents

Secure development lifecycle includes pointer-safety practices that reduce untrusted pointer dereference risk.

prevents

Application security requirements can mandate validation of pointers obtained from untrusted sources.

prevents

Secure architecture principles discourage direct use of untrusted values as pointers.

prevents

Secure coding standards explicitly forbid dereferencing pointers derived from untrusted input.
